BIRD GUIDING AROUND OSLO

NSKF meeting and an almost rarity


This weekend has been taken up with the spring NSKF (Norwegian Rarities Committee) meeting in Jæren – Norway’s premier birding area. Unfortunately spring has not yet come to Jæren either so there was hardly any migration to witness although on Sunday there was a little more life. As it is Jæren there are always birds to see though and the year ticks flooded in but there were no flocks of thrushes, no white wagtails and most of the ducks were over-wintering birds.

There was one real highlight though when I found a Green-winged Teal (amerikakrikkand) – a true rarity. I was with Tor Auden Olsen at Grudavatnet and we were pleased with a couple of Ruff (brushane) which were the first recorded in Norway this year and had both of us had looked through a flock of Teal (krikkand) a couple of times without finding anything more exciting. I was mentioning that Green winged Teal was perhaps our best chance of a rarity when on my third look through the flock I found one. I had to repeat myself a couple of times before Tor understood that I had actually found one, live in the flesh! It was at quite a distance and even though we were able to come closer on the other side of the lake it was always at least 300m from us. Never-the-less I managed some pictures – important to provide evidence convince our fellow NSKF members that we had seen it ;-) Or it would have been if the species was still a national rarity – I had forgotten that it had been degraded a year ago!
The Green-winged Teal (amerikrikkand) differs from its european cousins (krikkand) primarily by having vertical white stripes at the front of the flanks rather than horizontal white stripes over the flanks
the vertical white stripes are very obvious head on
Compared to the Oslo area the number of water birds cannot be compared. On the sea at Revtangen we had 8+ Great Northern Divers (islom), 300+ Common Scoter (svartand), 50+ Long-tailed Ducks (havelle), a 1st winter Glaucous Gull (polarmåke) heading north, and my first Ringed Plover (sandlo) and Purple Sandpipers (fjæreplytt) of the year. On Orrevatnet and the other lakes there were 1000’s of Greylag Geese (grågås) with a scattering of White-fronted (tundragås), Pink-footed (kortnebbgås),  Canada (kandadgås) and a single Bar-headed Goose (stripegås) amongst them. There were also hundreds of Wigeon (brunnakke) with smaller numbers of Teal and Mallard (stokkand) and with a pair of Gadwall (snadderand) and single male Shoveler (skjeand) and Pintail (stjertand) amongst them. Diving ducks were far less numerous with 100+ Tufted Ducks (toppand), 15 Scaup (bergand) and four Smew (lappfiskand) including a superb male and a male Pochard (taffeland) amongst them.
The only new passerine I had for the year was a single Meadow Pipit (heipiplerke) and there were no flocks of finches or buntings to be seen. Raptors were very scarce with just single White-tailed Eagle (havørn), Peregrine (vandrefalk) and Merlin (dvergfalk), 2 Goshawks (hønsehauk) and 2 Marsh Harriers (sivhauk). On Sunday though there was some sign of passage with a couple of Sparrowhawks (spurvehauk), and single Common (musvåk) and Rough-legged Buzzard (fjelllvåk) heading north.
Many of the birds were seen from the Kjell Mjølsnes’s house (host for the meeting) which must surely be the best birding house in Norway looking out over the particularly productive Ergevatnet.

One highlight was seeing a Woodcock (rugde) standing under a bush from the kitchen window – possibly the first time I have seen one on the ground in daylight!

daytime Woodcock (rugde) - look how large the eye is on this nocturnal wader

pair of Smews (lappfiskand) - this poorly exposed picture does not do justice to this magnificent duck

Finally, the weekend’s mystery gull. This 2k (or at least that’s what we believe) Herring Gull at Harvalandsvatnet on Saturday had me considering Caspian Gull due to its white head and some jizz features but in flight the underwing was far too dark so this is just a Herring Gull (although some may say of eastern origin).
interesting looking 2k gull



the dark underwing would seem to leave little doubt this is a Herring Gull
